being annoyed at my stock govenor made me look into a way to bypass it so i headed over to 240sx.org's FAQs and found this.
>After reading the first solution I looked into finding a simpler solution. Best of all, everything can be done at the computer. My car is a 89 with a 96 ka24de, but all the wiring and computer is 92. On my computer, there is a yellow wire with green stripe, 8th one over from right on harness. This is the vehicle speed sensor signal. Cut that wire. That is it. If you have a California car I think it will trigger a code, but for the rest of us, it is an easy trick. Your speedometer will still work because the signal comes from the tranny, goes to the gauges, THEN feeds the computer. I had to find a solution because my car comes very close to the speed limiter at the end of the 1/4. If anyone can beat the revlimiter let me know. I'm working on it.

After cutting what i thought was the correct wire (inside the engine bay, near the fuses) i realized that i hadn't cut the ecu wire and instead soemthing else. [car working fine]
Then i opened the kick panel and snipped the yellow wire with a green stripe on the right side. I took the car for a spin and noticed that my HICAS light was on and that my tach was not working. Got home, reattatched the wire. [car working fine]
Thinking maybe the right side wire i cut could have been the opposite wire, I cut the other yellow wire with a green stripe and nothing. [car doesn't start, smell of fuel indicating ignition problem?]
I undid the previous yellow/green wire, left the key in ACC and left the battery unplugged for a few minutes. [car starts, HICAS light still on, check engine light on] :!:
-From this i made the decision that the first ecu wire i cut was the Vehicle Speed Sensor (DTC 14). I also remembered that HICAS kicks in @ speeds above 50mph and the DTC14 would be neccesary for HICAS to function.-
Now I just want things back to normal, so i tried re-wiring everything as it was and doing the same trick with the battery and i've got nothing. [car won't start]
Help is appreciated! This is my daily driver. - dp
